SURGCAL APJLJIANCE,

Application led @ctober 13, 1920. Serial No. 416,732.

Y divers other operations.

ln designing the structure herein disclosed, lihave provided means for magnifying the part being operated upon and at the same time illunnnatmg the area at the point where the instrument is performing the operation. lt has, therefore, been an object.

of my invention to provide means for illuminating the area operated upon by means of an electric bulb or lamp, and arranging contiguous thereto a suitable lens the optical axis passing throughthe location of the instrument being used. Another object is the provision of a device that is extremely simple to. operate and which has its parts so ar` ranged that they may be disposed or packed in a relatively small space. A further object is the provision of a device that is simple in construction and made of a minimum of parts, and which is comparatively inexensive to manufacture. l prefer `to accomplish the divers objects of my invention'in substantially the manner hereinafter more fully described, and as more particularly pointed out in the claims, reference'being had to the accompanying drawing,in whichligure 1 is a perspective view vof my sur-- gical appliance showing the same in use.

Figure 2 is a longitudinal side of a portion of the structure shown in Figure 1, drawn p to an enlarged scale. Figure 3 is an end end of my appliance.

Figure 4 is a diagrammatic view showing view of the instrument v-the optical and light principles involved.

lin the drawings, similar reference characters are employed to designate the same parts throughout the views, and by reference thereto, it will be observed my appli- 19, 1916, for an incandescent electric lamp. 'l

As seen, this lamp comprises the elongated body 5 having a screw-plug at one end and the opposite end is provided with a hemi- Lspherical or lenticular closure 7 behind which, and within body 5 is a miniature electric light bulb (not shown).

The appliance, preferably, comprises a sleeve 8 of spring metal of cylindrical shape and having a longitudinal slit or split. The transverse inside diameter of sleeve 8 is normally slightly less than the exterior diameter of the lamp body v5 so that the former may be mounted upon the latter and retained in position frictionally.` An instrument holder .consisting of a suitable head 9 is mounted upon the under segment of sleeve 8 when in use, as seen in Figures'l, 2 and 3 of the drawings, and is provided with a bore that is oblique to the longitudinal axis of the lamp body. The instrument'for performing the operation has its shank inserted in the bore of head 9 and is retained therein by a set-screw 10 tapped transversely thereto into the head. rlhe instrument l have illustrated is what is known as an eye spud7 11, and as shown in Figures 2 and 4f of the drawings,

the operating point 12 is positioned at the point where the optical axis of the lamp lens 7 and the axis of the bore' in head 9 in-4 tersect. This point of intersection is substantially in the cone of light condensed or converged by the lenticular end 7 of the lamp so that the part being operated upon receives the maximum amount of illumination emitted from the lamp,`

Upon the upper segment of sleeve 8, and preferably intermediate the ends thereof, .il rovide` a pair of parallel lugs 13. Mounted between theselugs are the parallel clamping ears 14 of a circular rim frame 15 surrounding a convex lens 16. This construction permits the lens and rim frame 15 to be` moved to desired positions, such, for example, as shown in full lines in Figure 2 when it is desired to magnify the parts under operation, or may be folded flat down against the surface of sleeve 8 when magnification 35 j a suitable holder, a tool carried thereby, an

is notdesired. This positioning of the lens is such that it may be adjusted to bring the optical axis of lens 16 through the operating point of the instrument and through the optical axis of the cone of light condensed by the condenser 7 In other words, the -lens focuses upon the instrument point, and the part under operation and the lamp lens oondenses upon the same point, so that all three axes intersect at one point.

l have herein described and shown my invention in -connection with an instrument foi performing surgical operations, but it will be obvious that said instrument lmay be in the form of a mechanical tool, and the device used in connection with mechanical work as well as surgical. Other changes will be obvious to others skilled in the art, and I desire it understood that all such changes or modifications are fully contemplated and coming within the scope of the appended claims.

What I claim is: j

1. A surgical appliance comprising a suitable holder, alampl positioned thereon the light whereof is directed along a given axis, an operating instrument carried by said holder the point whereof is positioned in the optical axis of illumination, and a magnifying lens pivotally carried by said structure and movable into a position whereby the optical axis'thereof intersects the point of intersection. between the instrument and the axis of illumination of the lamp.

2. An article of'manufacture comprising electric lamp the lightwhereof is directed along a given axis'and illuminates the operating portion of the tool, and a lens pivotally co-operating with said holder and movable s0 that the optical axis thereof converges with the path of illumination and passes through the operating portion of the tool. 3. An article ofmanufacture comprising j a suitable-holder, a tool adjustably and re-A movably vcarried thereby, an electric lamp the light whereof is directed along a given i axis and illuminates the operating portion of said tool, and a lens hingedly carriedby the holder and movable toa position where the loptical axistlereof converges with thepath of illumination' and passes 'through the operating portion ofthe tool.

4. The combination with an electric lamp' having an elongated body, of a sleeve mounted upon and carried by said lamp body,v an operating tool adjustably carried by said sleeve4 whereby the working portion .of said tool is positioned in the zone of light emitted from said lamp, and a lens hingedly vcarried bysaidsleeve and movable to a position sogthat the Working portion of said tool is intersected by -the optical axis of said lens.

5. The combination with an electric lamp having an elongated body, ofv a sleeve mounted upon and carried by said lamp body, an operating tool adjustably carried l 6. A surgical appliance comprising a suitably shaped holder and having co-operating therewith an operating instrument, an electric lamp and a lens, said instrument, lamp and lens beingv adjustable with respect to each otherwhereby the optical axis of said lens converges to the point at which the plane of the instrument intersects the light axis of saidlamp. v

` 7. The combination with an electric lamp having an elongated cylindrical body, of a sleeve slidably mounted cnsaid lamp body, means for mounting an instrument oblique Vto the axis of said lamp body, whereby the outer portion of said instrument is positioned in the Zone of the maximum light flux emitted from said lamp., and a lens carried by said sleeve whereby the illuminated portion of the instrument'may be observed therethrough..v

8. The combination with a Surgical instrument, of means for illuminating the operating portion thereof, and a lens adjustably positioned so that thev illuminated porsplit cylindrical sleeve, an electric lamp havingan elongated body upon which said sleeve is frictionally mounted, a holder carriedby said sleeve, an operating instrument adjustably mounted in said holder the operating portion whereof is'positioned on the axis of said lamp, a frameqhinged on said sleeve opposite said holder, and a lens mounted in said frame and adapted toY be positioned whereby the loptical axis thereof intersects the axis of saidlamp at the point of illumination of said instrument.

1l. An article of manufacture comprising j a member adapted to detachably receivea sourceuof illuminationthe rays whereof are adapted to detachably maintain an instrument with its point in the axis of the cone of illumination, and a magnifying element pivotally secured to said member and rotatable in the plane common to the axis o the cone of illumination and the axis of said instrument.
